Product designer From art direction to vertical AI.

I've been designing for 18 years. I started in graphic design, moved into UX and designed WindowSight from its very first version, now on more than 30 million TVs. Now I'm building Fluxput, an AI copilot for field technicians.

Ask the copilot something.

This is how what I designed works: it answers from the manual and shows the page. When the answer isn't documented, it says so instead of making it up.

Hi. Tell me the model and the fault, and I'll tell you what the manual says.

About

I started designing at 19, in graphic design.

I trained in art and design at Escola Massana and spent seven years in advertising design. That craft is still there: typography, composition and a sharp eye for detail.

In 2016 I did a postgraduate degree in UX at the UOC and moved into digital product. Since then I've designed digital products, many of them from scratch.

Now I'm obsessed with designing AI that earns the trust of the people who use it: AI that cites where every answer comes from and knows how to say “I don't know”.
